Die Erfindung betrifft ein Kabel für ein elektrisches Gerät.The invention relates to a cable for an electrical device.

Aufgabe der Erfindung ist es, insbesondere für Gehäuse, die über kein Druckausgleichselement verfügen, eine Entlüftung bereitzustellen.The object of the invention is to provide a vent, in particular for housings which have no pressure compensation element.
Die Aufgabe wird durch das erfindungsgemäße Kabel gelöst.The object is achieved by the cable according to the invention.
Erfindugsgemäß ist ein Kabel für ein elektrisches Gerät vorgesehen, mit wenigstens einem elektrischen Leiter, der in einem Isolationsmaterial des Kabels eingebunden und von einem elektrisch isolierenden und wasserdampfdichten Außenmantel des Kabels umgeben ist,
wobei wenigstens an einer Stelle des Kabels eine semipermeable Membran angeordnet ist, die für Luft und Wasserdampf durchlässig und für flüssiges Wasser undurchlässig ist,
und im Bereich der semipermeablen Membran zumindest teilweise kein Isolationsmaterial des Kabels verbaut ist,
wobei die semipermeable Membran als Teil einer Manschette ausgebildet, die um das Kabel verbaut ist, wobei der Außenmantel des Kabels im Bereich der Membran unterbrochen ist oder Ausnehmungen aufweist, so dass eine Entlüftung des Kabels über die Membran gewährleistet ist.According to the invention, a cable for an electrical device is provided, with at least one electrical conductor, which is integrated in an insulating material of the cable and surrounded by an electrically insulating and water-tight outer jacket of the cable,
wherein at least at one point of the cable a semipermeable membrane is arranged which is permeable to air and water vapor and impermeable to liquid water,
and in the region of the semipermeable membrane at least partially no insulation material of the cable is installed,
wherein the semipermeable membrane is formed as part of a sleeve, which is installed around the cable, wherein the outer jacket of the cable is interrupted in the region of the membrane or has recesses, so that a venting of the cable is ensured via the membrane.
Dieses Vorgehen hat den Vorteil, dass für die Entlüftung eines Gehäuses keine separaten Bauteile benötigt werden, sondern eine Entlüftung allein durch das Anschließen eines erfindungsgemäßen Kabels realisiert werden kann.This approach has the advantage that no separate components are required for the venting of a housing, but a vent can be realized solely by connecting a cable according to the invention.
Besonders vorteilhaft ist es, wenn im Bereich der semipermeablen Membran die elektrisch isolierten Leiter aufgespreizt sind.It is particularly advantageous if the electrically insulated conductors are spread open in the region of the semipermeable membrane.
Wobei die Aufspreizung der Leiter wenigstens soweit erflogt, dass ein Flüssigkeitstransport entlang der Leiter infolge einer Kapillarwirkung unterbunden ist.Wherein the spreading of the conductors at least so far erflogt that a liquid transport along the ladder is prevented due to capillary action.
Dies Vorgehen hat den Vorteil, dass durch Aufspreizen der Leiter eine Kapillarwirkung für einen Wassertransport zwischen Leiter und Isolationsmaterial vermieden werden kann.This approach has the advantage that by spreading the conductor capillary action for water transport between conductor and insulation material can be avoided.
Besonders nützlich ist es, wenn im Bereich der Membran die Isolationsummantelung der Leiter zumindest teilweise entfernt ist.It is particularly useful if the insulation sheathing of the conductors is at least partially removed in the region of the membrane.
Bevorzugt sind zur Beabstandung der Leiter im Bereich der Membran Abstandshalter vorgesehen.Spacers are preferably provided for spacing the conductors in the region of the membrane.
Ebenso vorteilhaft ist es, ein elektrisches Gerät mit einem Kabel in der vorgenannten Art und Weise auszustatten.It is equally advantageous to equip an electrical device with a cable in the aforementioned manner.
Nachfolgend wird die Erfindung anhand von Ausführungsbeispielen unter Bezugnahme auf die Zeichnungen näher erläutert.The invention will be explained in more detail by means of embodiments with reference to the drawings.

Zur Entlüftung des Kabels
Zur Vermeidung eines durch Kapillarwirkung verursachten Wassertransports entlang des Isolationsmaterials
Das erfindungsgemäße Kabel
Problematisch an solchen Anordnungen ist, dass aufgrund der thermischen Volumenänderungen des vom Gehäuse umschlossenen Gases ein so genannter Pumpeffekt entsteht, der im ungünstigen Fall dazu führt, dass über die angeschlossenen Kabel Wasserdampf und ggf. auch bereits kondensiertes Wasser ins Gehäuse gezogen wird.The problem with such arrangements is that due to the thermal volume changes of the gas enclosed by the housing, a so-called pumping effect arises, which leads in the unfavorable case that steam and possibly also already condensed water is drawn into the housing via the connected cables.
Durch das erfindungsgemäße Vorgehen wird dieser Effekt zuverlässig unterbunden.By the procedure according to the invention, this effect is reliably prevented.
